FFmpegSource2 ! - ToiletDuck - 01.08.2023 @ selur and the likes, I have an very "simple" question.. First, you know i favor FFmpegSource2 over Lwlibavsource for filter preview in thet past, because it gave me quicker results.. Now, i have noticed an very and disturbing twist using FFmpegSource2 !! Is it possible alternate preview / source settings in vapoursynth tab, can affect final result of output file ![]() I mean, when i use certain settings for KNLmeans (vapoursynth), and play the results in mpc, i see many frame stutter!! Especialy when the camera is moving sideway's onscreen !! So, i have tested my theory, and choose Lwlibavsource again before adding the job.. And that seemed to fixed it !?? Realy? Or, i can stick to FFmpegSource2, but then i have to change one particular setting in knlmeans, → "Distance=x" (wich is very taxing on gpu btw) !! Cheers, TD RE: Faq = FFmpegSource2 ! - Selur - 01.08.2023 Both FFmpegSource2 and LWLibAVSource should be frame accurate, but both have issues with some sources. (Also LWLibAVSource does support using hardware decoding depending on the source and setting in Hybrid.) => yes, using different source filters can influence the output,... getting stuttering output/dropped frames is rather uncommon, but could happen depending on the source format.

Thanks selur for the confirmation.. And indeed, i just did an test run using old settings (prior to filter preview issue !!), and no more stutter.. funny, how just 1 setting out of a thousand possible configs, can influence the results dramatically !!! cheers, TD RE: Faq = FFmpegSource2 ! - Selur - 01.08.2023 Quote:funny, how just 1 setting out of a thousand possible configs, can influence the results !!!Every, setting can influence the result. ![]() Cu Selur RE: Faq = FFmpegSource2 ! - ToiletDuck - 01.08.2023 (01.08.2023, 17:31)Selur Wrote:Quote:funny, how just 1 setting out of a thousand possible configs, can influence the results !!!Every, setting can influence the result. Agree, to some degree... However, not every change is noticeable with the naked eye ![]() TSmuxing comes to mind ![]() cheers RE: Faq = FFmpegSource2 ! - Selur - 01.08.2023 Sadly, there is nothing I can do about these things especially when I can't reproduce them.

And that's another thing, all these issue's only happends with complete files, and not with short samples , Yet the sample are from the very same media file and seems to work just fine with wotever setting suddenly in hybrid ![]() ![]() cheers, td RE: Faq = FFmpegSource2 ! - Selur - 01.08.2023 You can also try whether remuxing the source to mkv before reencoding it helps.

LoL selur, are you pulling my leg ![]() ![]() I have shared that sollution in my other thread ![]() ...And no real sollution actually, since i have to remux all the files into m2ts anyway ... Because of other content i have to add, content that i can't add through hybrid because of (issues / crashes !!) !! (01.08.2023, 00:49)ToiletDuck Wrote: Update: RE: Faq = FFmpegSource2 ! - Selur - 01.08.2023 mkv is usually easier to open for filters like FFVideosource2 and LWLibAVSource. So my suggestion for remuxing to mkv beforehand mainly aimed for the preview issues. For muxing m2ts, Hybrid can either use tsMuxeR or ffmpeg, so you could also try whether it works better if you use ffmpeg as muxer. Cu Selur Ps.: m2ts is a mess (trying to calculate the overhead this container creates, before muxing, is just crazy) and in my opinion should never have been used for media files and only for streaming content,... ![]() |
