Main version 2.6 / Re: Filters without encoding?
« Last post by eumagga0x2a on September 26, 2018, 04:41:27 PM »
Let's say i want to adjust saturation/colors or i want to crop and change resolution....
How can i do it without encoding?

Some video players allow to adjust these values during playback. Everything else implies re-encoding the video.

How can i do it without encoding? i don't need to change codec because the files already have the one i want.

User interface and Usability / Re: Bitrate similar to original video after compression
« Last post by AQUAR on September 26, 2018, 01:14:10 PM »
Is there a reason for re-encoding with H265 and with the original bit rate?

Your approach:
Won't improve picture quality as this is a lossy process.
Won't change the file size as you maintain the original bitrate (not taking advantage of the HEVC codec).
H265 is an even more complicated codec and AFAIK would increase the difficulty in editing.
Uses a codec that is not well established yet.

Windows / error can not read CJK file name ...

error can not read CJK file name ...

hi

All Avidemux gateways have no way to do with the CJK file name ...

How
need help
97
hm... no answer  :( So I guess this cannot be done.

That's fine. I'm using Pavtube to compress all the videos, it works really great using this "keep original Bitrate" option. I just feed it dozens of videos and it convert them during the night. The result is at the end perfectly similar to the original videos, but with a better codec for editing.

Then I use the amazing Avidemux for cutting, trimming and what not.

Cheers.

Thanks eumagga0x2a.

I indeed managed to get the result I wanted putting much lower values for the GOP sizes.
Not sure what the i-frame is about then. I did some tests changing that value and couldn't really see any difference.

Cheers. Thanks for the answer.

Avidemux-French / Problème de commande 'Crop' sous mint avec Avidemux 2.5.4
« Last post by D.Conan on September 25, 2018, 12:18:13 PM »
Bonjour,
J'utilise un portable avec semble t'il un format d'ecran inadequat!!! Le fait est que:
Avec certains fichiers 'gros' en taille d'affichage l'affichage du filtre crop me donne l'image et juste les deux boutons 'retaillage auto' et 'effacer'. Les autres que je vois avec d'autres fichiers plus petits me sont inaccessibles. Pas moyen de réduire la fenêtre ou de la déplacer vers le haut.
C'est un peu ridicule mais efficace. Peu-être pourrais-je passer d'abord par une réduction des pixels de full HD a HD pour que l'affichage soit moins grand avec 'crop' mais bon.
Merci de m'aider a retrouver 'appliquer' 'valider' 'annuler' a l'ecran; ou une manière de faire.

Sincerement D.Conan.

Windows / Re: ADM - AND - FFmpeg alone on Win. XP => garbled frames.
« Last post by hiro on September 25, 2018, 04:39:23 AM »
Anyway, after MUCHO testing (3 days of nonstop hassle), here are some results. Can't be 100% affirmative of course but, on — 32-bit only — old Win. XP,

"x264 CLI version: core:133 r2334 a3ac64b" (dated 2013...)

recodes my "7-mn HuffYUV .avi test", to impeccable frames only / tested 4 times, to "make sure"...

while both "ADM", "FFmpeg CLI" & even "x264 VfW via VirtualDub or else" * garble several frames every time.

Code: [Select]
x264 --crf 24 --preset medium --profile high --level 3.2 -o RESULT-vid_no-sound.mp4 Test-7-mn-HuffYUV.avi
* "x264 VfW via VirtualDub" goofed much less frames, but at least one, out of my test vid.


About "ADM on Linux": I've read the above "32-bit warning" post (of course) but still wanted to give it a try. Guess I'll need a dedicated PC, but none at hand at the moment:

so I only tried to install ADM on an Xubuntu v°, running from a "live USB key"... NO WAY! "Get-deb" being down, I had to give up, after wasting some 24 hours; ADM (whatever v° I download) just REFUSES to install / I must say that I know NOTHING about Linux, though. What worked in ~2014 did not, anymore. 


Now, assuming that tests results are actually reliable (?? wouldn't bet a peanut, until further testing, on long footage), the silent .mp4 result vid. needs to be (re)muxed with its or some .aac audio stream

— using something ELSE than "FFmpeg", e.g. "Yamb/MP4box". Tested OK: no bad frames either.

Why? Because I also tried to save the test vid. w/ADM set to Copy & Copy, AND w/FFmpeg set to no recode... to end up with bad frames AGAIN: even in that case!


"In other words", back to the years ~2010 ** but "well", that's all I could get working (flawlessly).


[ ** as I intend to wear off those XP PCs until, say... 2050. Coming next: "How to encode to HEVC (x265) using a 1990 Amstrad PC?", since nothing's impossible, w/the help of Avidemux forum. ]


— BTW —, contrary to "FFmpeg" & "w264 VfW", since "x264 CLI" ONLY, recodes with no problem, doesn't it mean that "FFmpeg" & "x264 VfW" are somewhat buggy? OK: I KNOW that nobody wants to hear about 32 bits stuff anymore...  Have I read the above answers? Yes I HAVE.

But it's "kind of" disappointing; I'll have to modify quite a few of my help/instructions to those friends etc., who (stubbornly) stick to Win. XP. I more or less understand them, though, after messing w/Win. 10 since ~2015. What about Linux then? Well, that's an other story, + another forum too, after all...
