Our [WebTV Hosting](https://az-streamingserver.com/video-streaming-hosting/) servers require a uniform 720p format to seamlessly transition from one video to the next without crashing the player. Please use the following exact settings when exporting or converting your video files. --- ## Required Video & Audio Specifications ### Video Settings - **Container:** MP4 (`.mp4`) - **Video Codec:** H.264 (x264) - **Resolution:** 1280x720**Crucial:** If your video is a different aspect ratio (like a vertical smartphone video or a widescreen movie), you **must** add black bars/letterboxing to pad it out to exactly 1280x720. - **Framerate:** 30 FPS (Strictly Constant Framerate, *not* Peak/Variable) - **Quality / Bitrate:** Constant Quality (CRF/CQ) set to **23**, with a strictly capped Maximum Bitrate of **2500 kbps**. - **Keyframe Interval (GOP):** Exactly every **60 frames** (2 seconds). - **Color Space (Pixel Format):** 8-bit YUV 4:2:0 (`yuv420p`) - **Profile / Level:** Main / 4.1 ### Audio Settings - **Audio Codec:** AAC - **Bitrate:** 128 kbps - **Sample Rate:** 48000 Hz (48 kHz) ### Strict Filename Rules Web server playlists will fail if they read invalid characters in a file path. Your filenames **must only contain** uppercase/lowercase letters, numbers, underscores (`_`), and hyphens (`-`). Do not use spaces, ampersands (`&`), parentheses, brackets, apostrophes, exclamation points, or any other special symbols. - ❌ *Bad:* `My Promo Video (Final!).mp4` - ❌ *Bad:* `Big_&_Rich_Live_Show'.mp4` - ✅ *Good:* `My_Promo_Video_Final.mp4` - ✅ *Good:* `Big_and_Rich_Live_Show.mp4` --- ## Short on Time?

[Request Video Encoding Service](https://az-billing.com/billing/submitticket.php?step=2&deptid=2) --- ## Guide 1: How to Encode Using Shutter Encoder (Recommended) [Shutter Encoder](https://www.shutterencoder.com/) is a free, professional tool built on FFmpeg that handles our playlist padding and layout constraints perfectly. 1. Download and install [Shutter Encoder](https://www.shutterencoder.com/). 2. Drag and drop your video files into the main window. 3. Under **Choose function**, select **`H.264`**. 4. On the right panel under **Bitrates**, click the `VBR` button until it toggles to **`CQ`** (Constant Quality), and set the slider value to **`23`**. 5. Open the **Audio settings** panel, ensure the codec is **`AAC`** and change the bitrate to **`128`**. 6. Open the **Image scale** panel, check the box, select **`1280x720`**, and choose **`Letterbox`** in the adjacent dropdown. *(This automatically adds black bars if your video isn't natively 16:9).* 7. Open the **Advanced features** panel: - Check **Conform by**, select `Drop/duplicate frames`, and choose **`30 i/s`**. - Check **Force profile** and select **`Main`** to **`4.1`**. - Check **Colorspace** and select **`YUV 4:2:0`**. - Check **GOP** and type **`60`** into the box. - Check **Add custom parameters** and paste this exact text block:Plaintext`-maxrate 2500k -bufsize 5000k -sc_threshold 0 -keyint_min 60` 8. Click **Start function** at the bottom to process your files. --- ## Guide 2: How to Encode Using HandBrake [HandBrake](https://handbrake.fr/) is an open-source alternative, but you must manually configure it so it does not automatically crop out black bars to "save space." 1. Download and install [HandBrake](https://handbrake.fr/). 2. Open your file and go straight to the **Dimensions** tab. - Set **Resolution Limit** to `Custom` and type **`1280`** x **`720`**. - Set **Cropping** to `Custom` and make sure Top, Bottom, Left, and Right are all exactly **`0`**. - Check the **Pad** or **Fill** option to ensure the "Display Size" metric at the bottom reads exactly `1280x720`. 3. Go to the **Video** tab: - Select **Video Encoder:** `H.264 (x264)`. - Set **Framerate (FPS):** `30` and click the radio button for **`Constant Framerate`**. - Set **Constant Quality:** `23 RF`. - In the **Advanced Options** text area at the bottom of the tab, paste this exact parameter string:Plaintext`vbv-maxrate=2500:vbv-bufsize=5000:keyint=60:min-keyint=60:scenecut=0` 4. Go to the **Audio** tab: - Set **Codec:** `AAC` - Set **Bitrate:** `128` - Set **Mixdown:** `Stereo` - Set **Samplerate:** `48` 5. Choose your destination file directory and click **Start Encode**.
