How to watch DVD iso movies on Vizio Tablet VTAB1008?

How to watch DVD iso movies on Vizio Tablet VTAB1008?

Vizio Tablet VTAB1008 is a great tablet! It is so much better than a Kindle Fire in so many ways. The 8′ size doesn’t sound like such a big deal compared to the Fire’s 7″ screen but you would be amazed, it’s almost like a full size tablet. Also the fact that has a memory card slot is a big deal to me. Moreover, it keeps entertainment freedom at your fingertips with the Vizio 8″ tablet PC and watch your movies, TV shows and music in a thin, ultra-light design. Despite of the the viewing angles on its screen aren’t great, you can get nice picture when enjoying HD movies on the Vizio Tablet.


Looking for equivalent rendering profile as CLI: x264 --crf 18 --preset slower --tune film -o /data/output.mp4 /data/input.avi

I would like to have the same rendering profile that is used, when using preset=slower and tune=film with the x264 CLI command.
I tested such a x264-output-file with mediainfo and got the following:

cabac=1 / ref=8 / deblock=1:-1:-1 / analyse=0x3:0x133 / me=umh / subme=9 / psy=1 / psy_rd=1.00:0.15 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-3 / threads=9 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=60 / rc=crf / mbtree=1 / crf=18.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / ip_ratio=1.40 / aq=1:1.00

With kdenlive I managed to get the following ...


kdenlive automatically trims/crops audio


The versions I am using are: Ubuntu 11.10 and Kdenlive 0.9.2.
I made a 80 minutes documentary movie in English with Dutch subtitles.
When I rendered this project to MPEG-2 to burn on DVD, it worked fine.
Then I used the same files to make a version with Indonesian subtitles.
That means that the whole project was the same, I just changed the text in the title clips,
so that the Indonesian subtitles come at exactly the same place as the Dutch ones were.
For the rest nothing in the files was moved.
That is why I am surprised to discover that the newly rendered files (with the Indonesian subtitles)
suddenly have failures in one of the audio tracks.
At the end of each clip of the voice-over track, the clips get cropped,
so that one or half a word at the end of almost every sentence is missing.
It only does this with some of the files, not all, but I cannot see any difference in the original files,
nor with the original ones.


Kdenlive does not support x264 rendering with crf (constant rate factor) ?

My impression is, that the crf option is actually (and very unfortunately!) not supported by kdenlive yet. Why? Well I used a rendering profile with crf=20 and rendered. Then I changed the profile to crf=18 (leaving everything else unchanged). The filesize of the first rendering should usually be smaller than the rendering of the second file. BUT: It is not! The two files had the exact same filesize! Therefore it seems to me, that kdenlive actually just ignores the crf-option (and at the same time does not put out an error message).

Could perhaps someone confirm this?

Clip falsch trotz richtigem Trimmings


ich habe ein Projekt mit derzeit zwei Videospuren, wovonan einer Stelle zwei sich überlappen, und ich den Ton von der unteren und das Bild von der opren Spur brauche.
In meiner Timeline sieht es so aus:
Oberer Clip ist exakt so positioniert, dass er genau(!) Lippensynchron mit dem Ton läuft (es findet da ein Gespräch statt).
Spiele ich in der Timeline ab, sieht es auch perfekt aus.
Exportiere ich nun nur dieses Teilstück (kurz vor bis kurz nach diesem Clip) ist dieser Clip allerdings etwas versetzt (als hätte ich nicht richtig getrimmt).
Rendere ich den kompletten Film, ist dieser Clip aber, wie in der Timelinevorschau richtig.

Wieso rendert er den falschen Teil des Clips, wenn ich nur ein Teilstück rendere?
Kann das jemand bei sich bestätigen?

Jemand eine Lösung/Ahnung?
