MagicYUV codec problems

Mon Mar 14, 2016 12:47 am

So, apparently, when I specify MagicYUV, Full Size, and 60 FPS the resulting video becomes corrupted after a certain period of time. This is was during Device Recording, and happens even though the formats are supported. Though, it seems like it would happen in either of the other modes.

MPC-HC generated this error log about it, when trying to render the file. It seems there are improper frames? No program can render the file, regardless.

Also, and while this may not be related... But why does Bandicam always suggest YV12 to MagicYUV, even when the item you are recording is in a different colour space?

Hello!

How long did you record for?
Is it possible for you to send the corrupted video file to bandicam@bandisoft.com?

why does Bandicam always suggest YV12 to MagicYUV, even when the item you are recording is in a different colour space?

We've fixed the YV12 issue you mentioned.
We will release the fixed version in Bandicam 3.0.4.
Thank you for letting us know.

It seems to happen after I record for about 35~ minutes? I'm not sure if it's time, or size related.

Also, I doubt I could send you a 100+GB video file X_X

I was just curious if Bandicam will attempt to pass RGB ( or some form of YUV 4:4:4 ) frames to all VFW codecs in the new version, or only specific ones ?

The next version of Bandicam will allow you to use RGB as default in MagicYUV and Lagarith.

We don't have a plan for YUV444 at the moment.
We will consider it in the distant future.

Thank you for asking.

If you are selectively adding codecs in a whitelist style, could you add x264vfw to the RGB list ? It can handle RGB input frames and can also output compressed RGB.

Thanks for listening.

Hi Nyvoren,

We may not support the function you asked for because the performance of YV12 is better than RGB.

Hello!

Please try Bandicam 3.0.4 which was released on April 12, 2016.
- Download: http://www.bandicam.com/downloads/

The registered users of Bandicam are now able to use RGB24 as default with the MagicYUV Lossless codec.

So, apparently, the creator of MagicYUV has figured out why Bandicam has issues recording large (100GB+) MagicYUV videos.

"So we solved the issue with Cloudstrifeff7, this is just a summary of what was the problem.

First, the AVI created by Bandicam was incorrect, it had a corrupt index entry for the very first frame, pointing to a random location inside the file. This caused programs to present garbage data to the codec, which made it crash.

I couldn't find any program which could fix the index for an AVI with multiple audio tracks. ffmpeg cannot be told to ignore the index, DivFix++ croaks on large files, mencoder cannot handle multiple audio tracks, AVIMaster was still working after 2 hours.

So instead I fixed the codec to check more thoroughly if it gets garbage. This makes the first frame unreadable, but programs simply ignore it then.

The fix will be included in 2.0.0rc2.

Apart from this, Bandicam should also probably be fixed, as it creates a bad index for the first frame when recording large files."

Hello GenericPerson#432,

Did you send a file to the creator of MagicYUV?
For further investigation, is it possible for you to send one of the corrupted video files to bandicam@bandicam.com?

Thank you.

I can confirm that files above ~120 GB are corrupted and are not readable by VirtualDub (to extract Audio Streams) or Sony Movie Studio.

This is the main reason why I had to switch over to Dxtory, because my recordings end up at around 80 - 150GB mostly. Doing an automated split is not an option as there are always some seconds lost.

If this problem can be fixed I will gladly return to Bandicam, as this is still actively developed where Dxtory has problems with newer games, especially with newer implementations of OpenGL.

I am using MagicYUV Codec on 1440p resolution with 60 frames per second.
Do not ask for a sample file unless you provide a space to upload a 150GB file. I always need to hold back hard laughs when you ask for sample videos sent via email (there is usually a 15MB restriction on many mailservers). Please refrain from asking. I dont think anyone is able to fulfill this request.

I have found out, that it is not only a problem with MagicYUV. I have the same problems occur with UTVideo Codec.

Attached is the crashdump from VirtualDub accessing the 148GB file recorded with Bandicam.
Note the error occurs when accesing the first frame (0).

Obviously the Bandicam Encoder garbles all files that are above a specific size. Good that MagicYUV-Developer has a workaround for this issue with the next release. But the problem needs to be fixed by Bandisoft, as the same error arises with UTVideo.

Hello,

We are pleased to inform you that we've fixed the bug where there was an index error with over 150GB AVI files encoded by the MagicYUV codec.
It will be available in the next update which is scheduled for release next week.

We appreciate you all for your effort to report the issue.

Thank you.
