Part 4: You Might Also Want to Know

4.1 Why is rendering necessary?

Rendering is one of the most important steps in video processing. This ensures that your video plays seamlessly with all the applied effects and filters without any stutters in between. The playback in real-time becomes much smooth and seamless. Without the process of rendering, there will be a delay in the video and stutters will often be caused. This also ensures that the color filters added, additional background sound effects play along with the video without any delay.

4.2 Does rendering improve video quality?

Well, the rendering does improve the video quality by ensuring that the additional background effects that have been added to your video play seamlessly without any problems. When a video is incorrectly rendered, there is always a lag. Hence, we can say that without rendering, the video quality will differ and rendering does enhance the quality.

4.3 What is the difference between exporting and rendering?

Although both words are often used interchangeably, they have different technical meanings. When we say exporting, it essentially means that we save the final output video to our device. There are no technical enhancements that occur during the process of exporting. However, the rendering does have a change in picture quality. Rendering is the process where each frame is inspected and searched for any delays.

Closing Words

Well, we’ve looked at several different technical details pertaining to a video and mainly learned about the solution to the error «media player classic cannot render file«. This happens generally when we install corrupted videos from malicious sources on the internet. Another reason why this error arises is that the video format is unsupported by windows media player classic. We also looked at the difference between the process of exporting and rendering.

  • Possible Reasons for «Cannot Render the File» Error
  • Tip 1. Convert File to Compatible Format
  • Tip 2. Use Different Media Player
  • Tip 3. Repair MKV/AVI/MP4 Cannot Render File — Joyoshare VidiKit

Possible Reasons for «Cannot Render the File» Error

1 Install Error of Media Player

For example, most media players come with an installer on the Windows operating system. This safeguard is implemented by software programs to avoid future problems for valued users/customers. Various settings and routes are created throughout the installation process. If the program misses this, you’re going to have problems.

2 Wrong Media Player Configuration

In most cases, this is the case with Media Player Classic. Before playing your media files, every video player requires access to specific files. This contains codec files but is not restricted to them. Depending on how the media player on your device saved these files, they may no longer be accessible, resulting in «media player cannot render the file» errors. It’s possible that you consciously or inadvertently tempered your media player’s ability to access configuration files.

3 Unsupported Video Codec Files

Although MPC-HC does not officially allow third-party codec files, this is one of the most common causes of video problems in most other media players, not only MPC. While some media players offer the ability to automatically update codec files through the menu — settings, some don’t. Therefore, you’ll have to manually install codec files.

4 Damaged and Corrupt Media Files

When you first see this error, it’s virtually impossible to tell if your media file is faulty, particularly if you find that other media files also play the same ‘corrupt’ File. However, the most common reason for media player failures is file corruption.

Solution 1. Convert File to Compatible Format

Although MP4, MKV and AVI are widely used file formats, they might become incompatible with various media players owing to a lack of codec to result in media player cannot render the file error. Here’s how to use VLC to convert the File.


Step 1: Navigate to the Media option in the VLC media player. Step 2: Choose Convert/Save from the dropdown menu, or use the Ctrl + R keyboard shortcut. Step 3: To upload the MP4/MKV/AVI File that you want to convert, click Browse. Step 4: When the File is opened, choose Convert from the dropdown menu. Step 5: Now choose an appropriate output format for your media player. Step 6: Select a directory to store the result file and give the converted file a new name using the Browse tab. Step 7: To begin the converting process, click the Start button.

Solution 2. Use Different Media Player

The media player you’re using may have a problem. In this case, just switch to a different media player to test whether the video will play. Windows Media Player or VLC are two options. If the media player classic cannot render file issue continues, there’s likely a problem with the File itself.

Could not open file for writing?

enter image description here

I have been using blender for a few years and this is the first time I have come across this problem. I am running 2.79 on Ubuntu. I was trying render a short test video for a new project and I came across this error on the top of my blender feed. «Could not open file for writing» And occasionally I get the error «Python: RENDER_MT_presets» There is a triangle caution sign on the left of it. I am trying to write to the same folder of my last 6 videos. I found several videos just saying that I need to change the output source, but that didn’t work. I also found this post on the forum. Deleted .dvd file, and «Could not open file for writing.» I tried changing the permission for the folder, but again it had no effect. I am now confused by this and am hoping that someone could help.

$\begingroup$ The «Could not open file» error sometimes appears when you delete /move the rendered file and then try to render with that same name to that same location again. Try to change name of the output file. $\endgroup$

Aug 31, 2018 at 18:45

$\begingroup$ Check in compositing or materials if any input nodes require a local texture file. $\endgroup$

Sep 1, 2018 at 2:01

$\begingroup$ I wonder if the space in your folder name is the cause. If you open a terminal window and start blender from there, you should get some extra error info that may help figure out what the problem is. The RENDER_MT_presets error is referring to the preset menu above the render resolution, this would save to $HOME/.config/blender/2.79/scripts/presets/render/ . $\endgroup$

Sep 1, 2018 at 5:37

$\begingroup$ Hi John, Thanks for the reply. I’m not sure how to check that. I have never had to go into the deeper settings. I’m just curious as to why this was working 2 weeks ago, but now this is giving me this issue? $\endgroup$

Sep 1, 2018 at 17:17

$\begingroup$ You might have relative paths in your input nodes and might moved your blend file or the source images. To check go to the compositing view from scene. To debug precisely, maybe use the toggle system console from window and post the error $\endgroup$

In properties window, go to «Output» tab. Find «Output» heading within that tab. Check the «File Extensions» box (which is below the Output save path entry).

Just had the same problem, solved by re-linking the render folder location through the Output tab in the Properties Window, clicked on the folder tab and chose the same folder. Rendered correctly afterwards.

I managed to fix this error just by unchecking the «file extensions» in «output» option, then you have to add the extension manually directly in the final file

I had this problem, and it turned out to be Linux limiting the number of open files the the process (blender) may use.

Here is an annotated script that fixes the issue.

#!/bin/bash # find the current limit blenderProcessID="$(pidof blender)" currentLimit math-container">$blenderProcessID | tail -n1 | awk '7>' 2>/dev/null)" # Find the current number of open files used by blender: currentOpenFiles="$(lsof -p "$blenderProcessID" | wc -l)" # Calculate the difference delta=$((currentOpenFiles - currentLimit)) # If Blender has less files open then the limit, exit. ((delta > 0)) || < echo 'Number of files used by blender is under the current process limit.' >&2; exit 1; > # increase the limit by double the delta. newLimit=$((delta * 2 + currentLimit)) sudo prlimit --nofile math-container">$blenderProcessID" && echo "Increased open-file limit to $newLimit" >&2 

The idea here is that each user has a set of default limits that each new process runs under. This is queried and modified with the ulimit bash-built-in command.

However, once a process is running, the limits must be changed with the prlimit command.

Therefore, if you find you run into this problem often, you might consider changing the default for your user:

echo "ulimit -n $newLimit" >> ~/.profile 

which will take effect after you logout and back in (reboot etc.).

Cannot render the file как исправить

Im a new user- and I’ve encountered a quite basic problem.

Reaper won’t render.

When i try to render a project, i get to the rendering file window- which says ‘output file — no output’

‘Render status:
The target drive/path does not exist, is unavailable or in use’.

I’ve kept the output file directory and ‘render to’ settings at default- ie, sending to the Reaper Media folder. I’ve also tried changing them to no effect.

I’ve tried uninstalling reaper, and reinstalling.

Any suggestions from the community?

(I’m using 10.7.3 on a macbook pro. And the Reaper 64 bit version. )

try a different target path.

Thanks Mingustoo- is changing the target path the same as changing the output directory? (ie — where the rendered file is stored?).

If so, i’ve tried changing that — and I get the same result regardless. Not able to render.

Is there any thing else that might be the problem?

you might try clicking on the disk in finder and making sure you are permitted to write to that disk. I am new to Reaper as well(long-time Protooler), just trying to help a brother out.***edit**yes it should be ( to your question)

When you choose Render from the File menu, click the Browse button and set Reaper to render to your desktop— just this once— it’s convenient. If this works, set it to render to a place that makes sense for your workflow.

I’ve seen this problem when the target directory doesn’t exist— like after I’ve finished one project and deleted the detritus.

also . check the length of the filename.

I’ve had a similar issue. After many freezes . eventually did a render out, only to be stop with a similar message.

The filename was too long .

Many thanks for the suggestions- I’ve tried directing the output to the desktop, and using a very short file name. Nada!

any other ideas?

This is really frustrating, I sincerely believed Reaper might be a way of escaping the bad old pro-tools days.

Others can chime in here, but I think you need to trash some preference files, if you haven’t, and then rebuild permissions for your drive.

Have you tried the 32-bit version of REAPER? I’m grasping at straws, but at this point, we need to try more options.

Are you able to render WAV, MP3, anything?

There is some stunningly simple reason this isn’t working. Keep after it— ask every question you can. REAPER is great.

So what did you change between today and the last time it worked? Which of the suggestions in the thread did you try? What is your operating system and what is your render path?

Hi, I asked the original question. And so far it’s still a problem. Someone mentioned that it might be an issue with permissions. If anyone on the thread has a suggestion of how to resolve that — i’d be really interested to know.

The phenomenon you describe, happened to me for the first time when I upgraded version 6.14 to 6.15
I did not understand what was going on and had never encountered this problem before.
I quickly realized that the problem with the upgrade and something in version 6.15 was not working. At least for me.
I went back to version 14 and everything works perfectly and normally.
Today I tried to upgrade to version 6.17 again, thinking that in the meantime they have fixed the problem .
But again I encounter the same phenomenon.
Currently 6.14 normal in this respect. I recommend that you first go back there until they solve the problem for us.

I have this problem now after changing the SAVE drive to dropbox. It doesn’t matter what paths I set/change, I can’t render!

I had to re-save the project in a different folder and it worked. Maybe something to do with dropbox using the folder??

I had this message as well and nothing worked, then I realised that the folder I tried to output to had a space in the name, and it’s never been a problem before but suddenly with both 6.15 and 6.27 it stopped working (I was a bit overdue with an update as well so I updated trying to solve the problem), so I closed Reaper, renamed all my folders to names without ��� and spaces, and then it worked.

This happened to me, out of the blue yesterday.

Trying different things made it work — the advice above to have no spaces in folder names worked.

However the issue seems to be around whether or not you have ticked the box which adds the output file to a new track in the project. If you have previously rendered the project and so have a track in the project with the output file name then you get the error message. Delete the track containing the output file from a previous render and the error message disappeared and it worked again. I didn’t try incremental file name change, which also might have made it work.

And then, this morning, none of the above mattered and it rendered to an output file with a previous render in the project. However, when I did have the error message, doing the above, did make it work again!

Probably has nothing to do with everyone else’s issues, but thought I’d mention it, just in case.
I’m a Windows user, dabbling on a Macbook M1 Air. I had the same message yesterday, when trying to output to an external drive. What hadn’t occurred to me, initially, is that Mac OS doesn’t use the same formatting system as Windows, if your drive is formatted in FAT32 or NTFS it won’t/can’t write to it. They can be read, just not written to.
Renders fine to the Mac’s internal drive, however, it’s woefully slow compared to my Windows setup — 1m 4s for a 3 minute song, compared to 5s on the Windows machine.

I believe, if you format external drives to exFAT, they’re writable in both Windows and Mac OS.

NTFS is read-only on macOS. FAT, FAT32, and exFAT are read/write on macOS.

There are a few 3rd-party utilities that make NTFS read/write on macOS.
