How to increase brightness in avi videos?
 

Whatever I download is waayyyy too dark, 60% of the movies are usualy pitchblack, but in all three players where I tried them in, colour, contrast and brightness controls are locked.

This is a great question. I have come across problems like this also. Anyone have any ideas?

VirtualDub does it with the "filters".

http://www.virtualdub.org/

It is done via editing the original data? Does this mean that these videos are intentionally recorded so dark that even setting a gamma of 2.0 does not allow me to see more in the dark fields (but lesser in the lighter fields, if there happen to be any)?

I avoided AVI captures in the past, and if it is like this, then I can live very well with avoiding them in the future as well.

If the brightness is blocked, of course you need to re-encode the video with higher brightness if you want it higher.

So be it... what can I say, they put the word "capture" because it can do that to, but it's mainly a powerful linear video editing tool. By the way, VirtualDub does not install, you just click on the EXE, so no harm done if you do not like it or too intimidating for you, you just toss the folder in the trash and that's it. ;)

Yes, I just meant I find it so stupid to intentionally record movies that damn dark that one cannot see anything. Player software has brightness controls, like a TV. Why intentionally locking these controls? Stupid. It's always the case with AVIs. It's never the case with WMFs.

tried it anyway, with four different AVIs. And it did not load any of them - each of them, it complained, being another kind of additional format that it would not operate for not being compatible.

Well, worth an attempt, no AVIs for me, then.

Then you need to install a codec pack like K-Lite:

i have this problem with games aswell....fairly inexplicable...some games just are unplayable simply because they are far too dark...quite literaly a pitch black screen with some vague shapes moving about..no amount of gamma correction or brightness adjustment touches it..i have a program called powerstrip which sometime does the trick allowing me to adjust the gamma from there but still there are many games that this program is incompatible with..

foxes me

Thanks, that worked, though not easily accessible. Any way how I could save the lightened video without reserving several GB for what before was just 50 MB, and spending half an hour for the saving? The help file is for inside only, I did not understand even half of what I red.

Goto Audio and make sure that "Direct Stream Copy" is selected.

Then go to Video/Compress, select Xvid, Configure

Profile @ Level: Advanced Simple @ L5
Encoding type: Single Pass
Target quantizer: 3
Quality preset: General Purpose
Click Other Options, set "FourCC used" to DivX.

If you want to change wmv or MPEG2 files you need VirtualDub-MPEG2:

Or play the videos with BSplayer (comes with K-Lite), you can change the brightness and other things in Video/Color Controls.

Okay, I'll try that and blindly follow what oyu typed - I have no idea what it is that I am switching on that way. :)

You have to change your movie engine. In Windows, that means you're going to have to enable VMR9 to change things. I have no idea how to get that done with Windows Media Player. I think you have to enable VMR9 support for your video card, and then WMP will use it automatically.

Hä?

However, with Virtual Dub I found out now how to increase brightness - it is shown in the right of the two parrallel monitors, the left shows the original. But I did not find out how to save the manipulated version via the save-option. I tried that four times now, but the newly created AVI always was the old dark one.

:huh: The help file does not really elp to enlighten me. It's not really intuitive. Wwhat must I do?

A bit me, a lot Gizzmoe, gave you all the info you need to do so.

Here I made a quick HowTo in pictures ;-)

Load your video, than click on VIDEO and after FILTERS

After that choose ADD as shown below

After that you need to save it, Gizzmoe above gave you the setting to compress it nice nice! Thought I do not use Divx, I use Xvid.

Read the info, I know it;s hard a bit, but it is worth it, this program ROCKS!:rock: ;)

Oh wow! My turn to ask questions!

Perilscope how do I get a mouse cursor like that? Mine doesn't change orientation and size like yours! Please let me how where to get it. :88)

:smug: ;)

Ah yes, I am to that point exactly like you described it, Perilscope, sorry if my wording was not precise enough. But when I next save it then - it is the dark default setting again, although the setting produces lighter images within the program. The savin does not include the filtered movie, but resets it to default.
Is there a special hidden save option, maybe under a different label?

So Skybird did you manage to do it? If you didn't, and If it's not too much to ask, which AVI are you trying to brighten up, I can try the same video you are trying to edit. Tell me where or how to get it and I will try it too.

Alternatively, even better, tell us step by step what you do, maybe we can find out the point your are missing? If it works for us it must work for you. You must succeed.;)


Huh! It's not my cursor that you see on the pictures, it's a "Preset" addition found in PaintShopPro.:smug:

I also do and I gave him the settings for Xvid! Only the FourCC (the video codec identifier in AVI files) was set to Divx, that has the effect that the player uses Divx to decompress the video. I assume that more people have Divx installed than Xvid, they couldn´t play the Xvid video if the FourCC was set to Xvid. Xvid OTOH can play both Divx and Xvid files. So whenever you wanna share your video with lots of people it´s better to use the Divx identifier.

I understand what you mean Gizzmoe, and you are right, less problem for the majority.:up:

It's only that I am "over" protective of XviD. I think you know the story behind XviD and Divx back then, when the two split apart. I chose to follow XviD, and whenever I can I put forward XviD. But like you said for the majority its better the Divx FourCC.;)
