View Full Version : Droid X plays HD 720p MP4 file, samples in this post, need testing on HDMI plz

Today I have been playing around with some movie trailers and DVD Catalyst 4 (DVD Catalyst 3 users, click the cat-eyes to update for free), I figured why not.
I converted a 1080 trailer found on Apple's movie trailer website to 1280x720 just to see what happens, and guess what. it worked.
Initially I was using a cool trailer I found from the new Need For Speed Hot Pursuit game, which worked fine on standard 848x480 / 854x480 resolutions,

Streaming: (if it stutters, try playing it over wifi instead of 3G)

Download: (download to pc, extract, copy MP4 over to DX)
but encoded at 1280x720, it appeared jittery.

The original video already had a bit of a jitter in it during certain parts of the video (the landscape flyovers), but playing it on the Droid X, it just got worse. It might play better on an overclocked DX, but I am running mine at stock speeds.


I figured it might be the video bitrate used in the video, so to test, I increased it from 1500Kbps to 3000Kbps, but besides the better quality, I did not notice any difference in jitteryness. (good news: DX can handle 3000Kbps :))


I played a bit with reducing the framerate from 30 to 24 on this video, but with an existing jitter already, it didn't look right. I downloaded another racing trailer, "Fast & Furious", an oldie, which ended up having a lower framerate already, so converted that one, and it plays great on my DX

Because the files are natively supported on the Droid X (I tested all files in the stock "Gallery" app) they all should work fine over HDMI, but because I don't have an HDMI cable yet, I can not verify this.

The settings used in DVD Catalyst 4 for the Fast & Furious trailer:

To make sure the tests were fair, I used "Remove black bars from device" in Global Settings > Borders to make sure the resulting screen resolution was full 720p (1280x720)

Cars 2 teaser trailer, optimized for HDMI using the same settings as mentioned in first post

Thank you killathrilla,

The files created with DVDCat Free for Droid X will play fine through HDMI, as does the files of its bigger brother, DVD Catalyst 4. The last 2 files I posted are actually converted using quality settings that are a lot higher. Instead of the default 854x480 screen size, these are done at 1280x720 and also the video quality setting is double that of the Droid X HQ2 format (1500Kbps) found in DVD Catalyst 4. The files actually play without any issues on my Droid X, but because I don't have an HDMI cable myself just yet, I havent been able to test and see if they actually play fine on a TV as well, and if the quality is noticeably different.

If you do have an HDMI cable, could you please download either the Fast & Furios trailer (bottom of my first post) or the Cars 2 trailer (second post) and see if they play on your TV?

I do not have a cord but have downloaded a trailer at 720p resolution, the playback on my dx was a bit choppy for me.

Depending on the file you downloaded, they are on the edge of maximum capability of the Droid X in terms of playback. The Need for Speed trailer already had some jitteryness in the video, so this is also appearant in the created video files, which is why I switched to a different trailer. I don't have many widgets running (only 1 of the Beautiful Widgets, and thats it), so if you do have more widgets active, the playback will be affected. Creating files using the official specs is easy, but the 720p files are a bit higher than what Motorola actually specifies as the Droid X being capable of.

I picked up an HDMI cable for the Droid X, and while the files



do play fine, the quality isn't the same as the quality of the actual files themselves. I'm not sure yet, but it appears that the video gets down-scaled to fit on the Droid X screen, which is then redirected to the TV over HDMI.

Playing the exact same files using a HD media player looks a lot better somehow.

I find video fps settings of 1500 or higher messes up the audio playback on my x and creates about a one second lag so the music and voices are all messed up.

How do I fix this?

Higher than 1500Kbps is a bit of an overkill if you use the Droid X resolution for your files. If you use higher resolutions, the framerate is causing some complications, because the X has to downscale the video to fit on screen, which also takes up video processing power.

the 1280x720 3000Kbps video files I posted use a framerate of 24 fps. when I tried to use a framerate of 30fps, the playback is pretty bad.


I run my X at stock-speeds, and only have beautiful widgets enabled as a widget. Overclocking as well as many widgets on your home-screen can also affe3ct playback of video, especially if you are using high-quality settings.
