| Summary | 0000677: Mxf files have no timestamps | ||||
| Description | Previously, like in 2025, I had been rendering to ffmpeg > mxf > avcintra 100, for its balance of good q and liw file sizes. These files are then burned in handbrake to produce sharable movies. Haven't made any renders this year and had to make a movie just now. Put the mxf in hb and it can't read the video stream, outputs only audio. I was asking Krave AI what i could do, and it told me to remux the file with ffmpeg, but ffmpeg (just built it from git) reports no timestamps and aborts. So my question is, has cinelerra changed the output format of avcintra? Are there any format settings that could resolve this so that output mxf files contain timestamps? I tried these options: mxf_opmode=1a frame_rate=60000/1001 | ||||
| Steps To Reproduce | Render to mxf avcintra 100 Open output file in handbrake Try to output to any format h264 or h265 etc --files produced by cinelerra in 2025 are ok and produce video/audio mp4 --files produced now output no video | ||||

None of the presets with MXF containers work for me: AVC, DNxHR, etc. However, the same codecs in MOV containers work fine for me. Outside of CinGG, when using a GUI for FFmpeg (I don't use HandBrake, but Shutter Encoder), the rendering process (avc_intra_100; mxf) goes smoothly. |
