![]() ![]() As far as we know, MP4 container, AAC codec is the best choice when compatibility matters in Avidemux. It may contain some video or audio codes that Avidemux can’t support. Now in this article, we aim to help you quickly solve the issue.įirst you can check the info of the MOV video. However, when searching online, we found more than one guys met troubles while trimming, cutting MOV files in Avidemux. ![]() Can anybody advise me what i'm doing wrong? I'm new to Avidemux & I don't know much about video formats and so any help is appreciated."Īvidemuxis a free and open-source video editing program designed for video editing and video processing. In any case, please update to the latest Avidemux nightly (on Linux you can build your own from the latest git master especially easily, else please resort to those from appImage4Buster directory for Linux distributions with GLIBC library 2.28 or later or to builds in appImage4 for very old distributions) to see more of the extradata in the properties dialog, let alone numerous fixes and enhancements since 2.7.8, but I strongly doubt that you will be able to reproduce the extradata of the source with x264 configuration in Avidemux.How to Trim/Cut/Shorten MOV in Avidemux Correctly ![]() As you mentioned 50 vs 25 frame rate, I suspect that the origin of the source was field-encoded interlaced MPEG-2 (field rate: 50 fields/s) which translates to 25 full pictures per second.Īverage framerate slightly below the standard value is an artifact of cuts in copy mode in open-GOP type H.264 streams with B-frames in Avidemux, because we drop so-called early B-frames not used for reference, resulting in small gaps in DTS (not in PTS!) right after each cut point. The resolution 720x576 is the usual PAL DVD standard definition resolution with overscan (704x576 with 8 pixel margin left and right) and 16:11 the standard pixel aspect ratio for widescreen (16:9) display, meaning that the origin of the source was probably MPEG-2, not H.264. (the remainder past the first 10 bytes was dropped until very recently) you absolutely cannot merge these videos in copy mode. In addition, Avidemux cannot find any keyframe in the exported clip while it finds several at the same position of the original file Quote=Īnd the final I get with the MPEG AVC (x264) codec and the resample I/S filter on Avidemux 2.7.8 on Linux MintĮxtra data: 01 64 00 1F FF E1 00 18 67 64 ![]() So, how can I get all the parameters from the original video and copy a clip between any frames with the exact same settings as the original codec, or how can I remove a part between no keyframe frames without reencoding the whole video? However, I get the same final error even if I set the rate to 50 or 49.99 (impossible to set the third digit). The former is still changed to 25 even if I use the Change the I/S rate filter to set to 50 or 49.998 but change with the Resample I/S rate filter. This is true, the tiny set of codec parameters I can get shows the fps has change from 50 to 25 (why!?) as well as the pixel ratio. Playback of the video saved in copy mode may stop at this point. QuoteCodec or codec settings across a cut point do not match. So I tried to cut and reencode a small part around the start and stop of ads in order to get a clip starting with a key frame.īut I get an error message saying the clips don't have the same codec setup, so video reader should fail to read it. But as my PC is old and slow (1 min of video requires about 5 min to be reencode in h264 at same resolution) I would like not to reencode the whole file.īut the copy mode is available only when cuts are made on key frames.Īs you guess, ads never gently start and stop at key frames, so I have to reencode the whole file. I would like to remove ads from within a show I have recorded with VLC. ![]()
