KingConvert Tutorial: Convert Any Video to Sony Ericsson XPERIA X10 Format

Best Settings for KingConvert: Optimizing Videos for XPERIA X10 PlaybackThe Sony Ericsson XPERIA X10 is an older smartphone with specific playback limits — to get smooth, high-quality video on that device you need to match resolution, bitrate, frame rate, and codecs to what the phone handles well. This guide walks through the best KingConvert settings (step-by-step and why they matter), plus tips for preparing source files and troubleshooting common problems.

Quick compatibility overview (what XPERIA X10 supports)

• Display resolution: 480 × 854 pixels (FWVGA), 4.0” screen
• Typical friendly video resolution: 480×800 or 480×272 (for landscape or portrait-focused playback)
• Container & codec commonly supported: MP4 (H.264 Baseline, AAC-LC)
• Maximum practical bitrate: ~800–1,200 kbps for video (higher can stutter)
• Audio: AAC-LC, 128 kbps, 44.1–48 kHz, stereo
• Frame rate: 24–30 fps (match source; avoid >30 fps)

Why these settings matter

• Resolution and aspect ratio: matching or downscaling to the phone’s screen prevents wasted CPU and memory, reduces artifacting, and avoids letterboxing or incorrect scaling.
• Codec/profile: XPERIA X10 favors H.264 Baseline profile (hardware-accelerated). Using Main/High can cause playback failures or heavy CPU use.
• Bitrate: too low produces blocky video; too high causes stuttering, dropped frames, or failure to play. Aim for a balance.
• Frame rate: converting to a higher-than-source frame rate wastes bitrate and can introduce judder.
• Audio settings: keep AAC-LC at moderate bitrate and standard sampling rate to ensure compatibility and good perceived quality.

KingConvert recommended export preset (step-by-step)

1. Source import

   • Open KingConvert and load your source file (MP4, MKV, AVI, etc.). If the source is interlaced, deinterlace it first.

2. Container / Format

   • Select output format: MP4 (MPEG-4 Part 14).

3. Video codec

   • Codec: H.264 (x264 if available)
   • Profile: Baseline
   • Level: 3.0 (compatible with 480×800 at the bitrates we recommend)
   • Encoder preset / speed: choose a balanced option (e.g., “medium” or “fast”) to keep reasonable encode time with good quality.

4. Resolution & aspect

   • If the source is widescreen (16:9), set resolution to 480×272 for landscape-focused playback apps, or 480×800 to use full screen (crop or letterbox as needed).
   • Keep aspect ratio locked to avoid stretching. Use letterboxing (black bars) if you must preserve the entire frame.

5. Frame rate

   • Set fps to match source (commonly 24, 25, or 30 fps). Do not exceed 30 fps.

6. Bitrate settings (video)

   • Use Constant Bitrate (CBR) or Average/Target Bitrate (VBR) with a cap:
     • For 480×800: 900–1,200 kbps (start at 1,000 kbps for good balance)
     • For 480×272: 600–900 kbps
   • If file size is critical, drop by ~200 kbps; if quality is critical and playback is smooth, you can experiment up to 1,500 kbps but watch for stutter.

7. Keyframe (GOP) and advanced

   • Keyframe interval: 2–3 seconds (48–90 frames depending on fps). A value around 60 for 30 fps is fine.
   • Enable CABAC: No (CABAC is part of higher profiles and may not be supported).
   • B-frames: 0 (Baseline/profile compatibility).

8. Audio settings

   • Codec: AAC-LC
   • Channels: Stereo (2 channels)
   • Sample rate: 44.1 kHz or 48 kHz (44.1 kHz is safe)
   • Bitrate: 128 kbps (96 kbps acceptable for smaller files)

9. Encoding mode

   • Two-pass VBR gives best quality-to-size ratio; use if you have time. Single-pass VBR is faster and acceptable.

10. Subtitle & metadata

    • Burn subtitles into the video if the X10’s player doesn’t support external subtitle files. Otherwise include SRT alongside MP4.

11. Save/export

    • Choose a sensible filename and folder. Run a short test clip (30–60 seconds) first to confirm playback on the device before batch converting.

Sample KingConvert preset values (concise)

• Format: MP4
• Video: H.264 Baseline, Level 3.0, Resolution 480×800 (or 480×272), fps = source (≤30), bitrate = 1000 kbps, B-frames = 0, CABAC = off
• Audio: AAC-LC, 128 kbps, 44.1 kHz, stereo
• Encoding: 2-pass VBR (optional)

Preparing source video for best results

• Stabilize and crop to remove black bars before encoding to avoid wasting bitrate on empty areas.
• Deinterlace interlaced sources (select “deinterlace” option) to avoid combing artifacts.
• Normalize audio peaks if dialogue volume varies widely.
• If source has strange aspect ratio, crop/pad to match chosen output resolution to avoid automatic stretching.

Troubleshooting common playback issues

• Playback stutters: lower bitrate (try 800–900 kbps) or reduce resolution. Also test with single-pass vs two-pass.
• No audio: ensure AAC is used and not a surround codec; convert multi-channel audio to stereo.
• File won’t play: check H.264 profile (use Baseline) and container (MP4). Re-encode with Level 3.0 and B-frames = 0.
• Subtitle not visible: burn subtitles or convert them to the device-supported format.

Batch conversion tips

• Create a device preset in KingConvert with the above settings so you can apply it to multiple files.
• Run overnight for large batches using 2-pass VBR if you want best quality.
• Periodically copy a converted file to the X10 and test to ensure settings still work across different source types.

Final checklist before converting a full library

• Set container to MP4, codec to H.264 Baseline, Level 3.0.
• Resolution: choose 480×800 or 480×272 and lock aspect ratio.
• Bitrate: ~1000 kbps (adjust based on file size vs quality).
• Audio: AAC-LC, 128 kbps, 44.1 kHz, stereo.
• Frame rate: match source, ≤30 fps.
• Disable B-frames and CABAC, consider two-pass VBR.
