Another really necessary thing that is missing is deinterlacing. I can do this myself by adding -vf yadif=1 to the mplayer command line but I don't know if this is doing the best job or not.

Greetings freddyzdead!

Please accept the fact that ViDrop is intended for users with no advanced knowledges about video conversion. It does a great job and should be used for mobile device with 2-7 inch screens.
For monitors and TV's you should consider other conversion softwares that requires some degree of video conversion knowledges, such as AutoGK or use(learn) the scripting language of Mencoder itself(for that take a look here:
http://www.mplayerhq.hu/DOCS/man/en/mplayer.1.html#CODEC%20SPECIFIC%20ENCODING%20OPTIO NS%20(MENCODER%20ONLY)
), case in which you can paste the resulted scripts in ViDrop's lower screen...

Hth.

Best regards.

Hello the_provider:

Yes, I realize that ViDrop is intended for portable devices and all that. It does a beautiful job. I don't like Gordian Knot; I use Virtualdub for serious work, but it is annoying that I have to go back and start it over to do the 2nd pass. ViDrop kindly does this for you, so it really speeds things up.

The resize filter I use in Virtualdub is Precise Bicubic, which is the only one that I use; any other gives artifacts. So all I want to do is tell Mencoder to use precise bicubic as well. It already occurred to me that I could add it to the command line, the same as I do for deinterlacing, if I knew the command to do so.

I have looked through the Mencoder docs and I don't see any way of specifying the resize algorithm. Maybe I missed it, but I really did look. Maybe it's called something else? Ok, I looked again and found it under "scale", which says also see -sws... it's pretty ambiguous to me; doesn't make much sense.

That is what I get:

I've just checked: the issue seems to take place with mkv-files having internal subs. With xvid avi-files it does not happen.

In the case of an mkv-movie, how can I choose other external subs, or at least to disable the internal ones?

Thanks a lot.

This is actually a bug in mencoder, not vidrop. I was able to fix it by downloading the latest version of mencoder for windows (link here) and dropping a the fresh mencoder.exe into the vidrop folder. Then tah-dah... no more overlapping subtitles in "add borders" mode.

So all lokster needs to do is release a minor version with a new mencoder binary. Cheers, lokster, for making this awesome app!

EDIT: DOH! Ignore me, the upgrade didn't fix it. It's definitely an mencoder problem though, just need to find the right tweaks. I tried http://lists.mplayerhq.hu/pipermail/...ry/009850.html but that didn't do it for me

You can set both passes to be performed as batch jobs...but that's another topic for another forum...sorry but I have to stop here.

As much as I understand precise bicubic is the default video filter used by mencoder:
2 bicubic (good quality) (default)
so you don't have to worry anymore. BTW, I always use lanczos in Vdub...
Best regards.

Hi Lokster,

I have a new issue. I've just purchased a new Rockchip 2706 PMP with the resolution 480x272. I've found out that viDrop simply does not recognise this resolution.

Could you please provide a new preset with this resolution?

Thanks!

Edit: The problem occurs in the mode "Add borders" which I like very much.

Edit: The problem suddenly disappeared. Obviously there is some instability of viDrop.

I hope... :)

Check out the new "Split" feature too.

Hi Lokster!
You're the man mate, this piece of software is MARVELLOUS! Many many thanks and compliments :lol:


One tiny bug I found: I tried the "split" function and it does split as it says, but it appears to me to produce 5 mins chunks only.
This is because the "Split every >>" value changes the start point for the split (mencoder parameter "-ss"), but not the end point (mencoder parameter "-endpos").

E.g.
For splitting every 10 mins, the code generated is
-ss 0 -endpos 300
-ss 600 -endpos 300
-ss 1200 -endpos 300
...
which produces chunks of 5 minutes (300 seconds) each starting at every 10 minutes (0, 600, 1200 seconds).

I believe that the correct code should be:
-ss 0 -endpos 600
-ss 600 -endpos 600
-ss 1200 -endpos 600
...

Workaround

1. Copy/paste the generated code from viDrop to any text editor.
2. Change the "-endpos 300" to "-endpos 600".
3. Copy the code back in viDrop.
4. Run the batch.

Hope this helps :)

Why in the Earth would you want to do something like that, in the first place?
And second, in one of my previous posts you can find a link to Mencoder instructions, look for it and have fun...

Best regards.

Re: viDrop - free open-source converter for RockChip players
 
Sorry my english is not good. This also, i dont be smooth tell. Virtual dub can do join but my mp4 player (Ingoo In-T500) cant open virtualdub avi file...

i was tell be seample virtualdub proccess. can do Mencoder like this join proccess?

Excuseme again for my english.. :)

Virtualdub's AVI files are not the same as those played by cheap mp4 files. It seems to be a variation of xvid. If you want to use virtualdub in order to append files, boost audio gain, HVC, brightness etc., you will still need to run the file through mencoder to produce the correct avi format. This is the same thing I do. I use virtualdub to add filters and such, then run it through AVI converter (based on mencoder).

Arkadash, why do you want to join files? It makes more sense to split large files...
